Not IOS 11 compatible – Birthday Sweet - Birthday calendar & reminder for Facebook Review

Love the app but ever since I updated my iPhone to IOS 11 , it no longer is compatible and won’t open up. Would love to see an update ASAP on this so I can see all the information I put in there. I am missing peoples birthdays because this app isn’t working. I don’t have any birthdays saved anywhere else and if this doesn’t get updated all my data in here will be lost and I will not know anyone’s birthday.
